What are the requirements on a Linux binary in order to drill down to hotspots and view function names?
In order to drill down to hotspot and view by function, the Linux binary must have symbols. For example, if the binary is an executable, then it should not be stripped (this can be checked by using the nm command on the executable). If the binary is a shared library, then it must have at least dynamic symbols (this can be checked by using the objdump command on the library). If the binary is a Linux kernel, then the kernel file must have symbols and be in non-compressed, non-bzImage format.
